A federal grand jury is looking into loans made to Kansas Governor Sam Brownback's re-election campaign.
The jury has ordered the state's ethics chief to testify next week as part of its investigation, according to a subpoena obtained by The Associated Press.
Carol Williams with the Kansas Governmental Ethics Commission was summoned to appear before the grand jury Wednesday in Topeka.
She was ordered to provide documents pertaining to loans Brownback's campaign received in 2013 and 2014.
The subpoena doesn't say which specific loans are being investigated, but the only loans listed on campaign disclosure reports for those years are one from Brownback himself and others from Lt. Gov. Jeff Colyer.
Colyer loaned Brownback's campaign $500,000 in August - the third such loan the governor's running mate made to their re-election bid.
Colyer told the AP in August that the two short-term loans he made to Brownback's re-election campaign are examples of the good stewardship Kansas residents expect from government officials.
Colyer said, "It's good money management, that's all.... We manage our campaign well - that's it."
Brownback also loaned his campaign $200,000 during the last reporting period.
The governor's office said it was unaware of the investigation.
The U.S. attorney's office declined comment.
